Purging Inactives after an allotted time
I just noticed, Because I was curious for the last 3 weeks, even though I have it set to purge every 7 days that it keeps logging "Nothing to remove... up to date. Nothing to remove... up to date." 

The last time anything was purged from what the logs say was 8/29/2018 and that was 3 weeks ago :) 
I haven't changed anything. So I dont know why it would stop working ?

When you got the feel something is acting wrong, then check random entries of the data-file against your "inactiveAfter" setting.

When it stopped working, for whatever reason, then there will exist entries /datetimes which greater than your limit.
